Description
Technical field
The utility model relates to a kind of waste heat recovery type compressed air drying purifier, the compressed air drier that especially a kind of used heat utilizes.
Background technology
In the prior art, a kind of used heat regeneration absorption type drying machine is arranged, it utilizes the heat of air compressor machine high-temperature exhaust air, and adsorbent is regenerated; It combines heatless regeneration and hot regeneration techniques is arranged, and can produce the dry air of low dew point, and not need air blast and heater.Its operation principle is:
The high temperature malaria at first directly enters regenerator, and the adsorbent that has absorbed moisture is heated.High temperature air more than 141 ℃ has enough energy, and moisture is parsed from adsorbent.The relative humidity of high temperature air is lower, compares with the humidity of adsorbent, and enough difference are arranged, and therefore the large quantity of moisture that parses can be taken away.
Then, the high temperature malaria, flow through water-cooling type heat exchanger cooling after, reduced temperature, discharge a large amount of liquid moisture, be filtered the device filtering, enter drying machine again and carry out drying processing.This process is similar to common heatless regeneration drying machine.Air after dry the processing has used through just providing behind the after-filter elimination dust.
Regenerator after finishing heating process, need cool off and purge, so that drop into dry work subsequently.The method that cooling purges is: allow whole high temperature compressed airs after supercooling, filtering, all enter drying tower and carry out the drying processing.Simultaneously, allow the regenerator venting reduce pressure, and draw a small amount of low temperature dry air from the gas outlet of drying machine, regenerator is purged, purge gas is discharged drying machine.Purge gas can be taken away moisture remaining in the regenerator.Because evaporation, cooling, the temperature of regenerator has reduced, and moisture has been taken away, and therefore can produce dew point preferably.After purge finished, regenerator boosted.Whole regenerative process just is through with.Purging air consumption is 5% of total air inflow.The ratio of purge time and heat time heating time is about 1: 1.Therefore, the average air consumption of whole circulation is about 2.5% (5%/2).
Drying tower is proceeded dry the processing, up to the maximum adsorption ability that reaches adsorbent under the control of energy saver.Switch whole flow process counter-rotating then.
Because combine heating and purge temperature-fall period, the temperature of adsorbent is reduced, therefore the fluctuation of the dew point when switching is lowered to minimum.
Though prior art has solved: the dew point that reduces output gas; Reduce air consumption; Energy consumption cost is low; Do not need heater, air blast.But air consumption still exists, and energy consumption will be consumed, and has only air consumption is reduced to zero, has just really solved the loss problem of the energy, makes energy consumption cost minimum.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of regeneration consumption gas problem that can solve absorption type dryer is provided, i.e. regeneration consumption gas is zero, thereby reaches the zero gas consumption waste heat recovery type compressed air purifier of saving energy effect.
The purpose of this utility model is finished by following technical solution, it mainly contains two and is interconnected at drying tower A, B together, that have same structure mutually with pipeline and valve, it is characterized in that described high temperature humid air passes through pipeline, link to each other with the upper oral part of drying tower A through a DV5 Pneumatic butterfly valve, infraoral at drying tower A links to each other with rear portion cooling through a DV3 Pneumatic butterfly valve, after connecting a gas-liquid separator again, be connected in drying tower B lower ports through a DV2 Pneumatic butterfly valve; After connecting a DV8 Pneumatic butterfly valve from the upper port of this drying tower B with pipeline, pick out described dry decontamination air through post-filter; Described high temperature humid air by pipeline also and be connected to a DV9 Pneumatic butterfly valve links to each other with aftercooler again; Described DV8 Pneumatic butterfly valve also links to each other with another DV15 Pneumatic butterfly valve, links to each other with drying tower A upper port by this DV15 Pneumatic butterfly valve again; Described drying tower B upper port with pipeline also and be connected to a DV14 Pneumatic butterfly valve and links to each other with drying tower A upper port by this DV14 Pneumatic butterfly valve, and this drying tower A lower ports links to each other with post-filter through a DV10 Pneumatic butterfly valve; Described high temperature humid air by pipeline also and be connected to another DV6 Pneumatic butterfly valve and directly links to each other with drying tower B upper port, links to each other with after cooler through a DV4 Pneumatic butterfly valve from drying tower B lower ports; Described gas-liquid separator is after link to each other with drying tower A lower ports after the DV1 Pneumatic butterfly valve connection; The upper port of described drying tower A is connected in post-filter through a DV7 Pneumatic butterfly valve.
The utility model belongs to improvements over the prior art, and the simple and easy to use and reliable characteristics that it has kept original structure adopt special technological process simultaneously, and making regeneration consumption gas is zero, thereby can reach characteristics such as saving energy effect.
